For metal and plastic pipe, <br />compact the backfill in the cover zone to a density of at least 95% of the Standard Proctor <br />maximum density as determined by AASHTO T 99, Method C. <br />125 -9.2.2 Exceptions to Pipe Density Requirements: Compact the backfill to <br />a firmness approximately equal to that of the soil next to the pipe trench in locations <br />outside the plane described by a two (horizontal) to one (vertical) slope downward from <br />the roadway shoulder line or the back of curb as applicable. Apply 120 -9.2.1 when <br />compacting side -drain pipe backfill under driveways serving a property that is not a single <br />residential lot. <br />125 -9.3 Additional Requirements: <br />125 -9.3.1 Frequency: Conduct QC Standard Proctor maximum density <br />sampling and testing at a minimum frequency of one test per soil type. The Verification <br />test will be at a minimum of one test per soil type: <br />Test Name <br />Quality Control <br />Verification <br />Standard Proctor <br />One per soil type <br />One per soil type <br />Maximum Density <br />One per four LOTs and for <br />Density <br />One per LOT <br />wet conditions, the first lift <br />not affected by water <br />One per Standard Proctor <br />One per Standard Proctor <br />Soil Classification <br />Maximum density <br />Maximum density <br />ARTICLE 125 -10 (Page 173) is deleted and the following substituted: <br />125 -10 Verification Comparison Criteria and Resolution Procedures: <br />125 -10.1 Standard Proctor Maximum Density Determination: The Engineer will <br />verify the Quality Control results if the results compare within 04.5 PCF [72 kg /m3] of the <br />Verification test result. Otherwise, the Engineer will take one additional sample of material <br />from the soil type in question. The State Materials Office or an AASHTO accredited <br />laboratory designated by the State Materials Office will perform Resolution testing. The <br />material will be sampled and tested in accordance with AASHTO T 99, Method C. <br />The Engineer will compare the Resolution test result with the Quality Control <br />test results. If the Resolution test result is within0 4.5 PCF [72 kg /m3] of the corresponding <br />Quality Control test results, the Engineer will use the Quality Control test results for <br />material acceptance purposes for each LOT with that soil type. If the Resolution Test result <br />is not withino 4.5 PCF [72 kg /m3] of the Contractor's Quality Control test, the Verification <br />Test result will be used for material acceptance purposes. <br />March 2007 01000 -36 03- 4122.D T <br />
